Abstract
Abstract Smoke retardant vinyl chloride and vinylidene chloride polymer compositions are obtained by including therein a synergistic mixture of (A) at least one melamine molybdate or substituted melamine molybdate and (B) at least one compound selected from the group consisting of CoCO 3 , Co 2 O 3 , cobalt (II) acetylacetonate, cobalt (III) acetylacetonate and hydrates thereof. Substantial smoke retardation is also obtained by including the above compounds individually in the vinyl chloride or vinylidene chloride polymer compositions.
